The "cartoon killings" in Paris were carried out by Cherif Kouachi and his brother Said Kouachi. The attack took place at Charlie Hebdo, a satirical, political magazine in January 2015.
The Kouachi brothers were Islamist terrorists armed with assault rifles who forced their way into the offices of the satirical weekly newspaper. They killed 11 people and injured another 11 others in the building before killing a French National Police officer outside. The brothers identified themselves as belonging to an Al-Qaeda branch in Yemen that took responsibility for the attack that was carried out reportedly in response to past published cartoons of the Muslim prophet Muhammad in the magazine. The magazine had been the target of previous attacks, and its offices had been firebombed in the past.
